NAME

6       sconsign - print SCons signature file information
7

SYNOPSIS

9       sconsign [options...] [file...]
10

DESCRIPTION

12       Displays the contents of one or more sconsign files, the signature
13       database files used by the SCons build tool.
14
15       By default, sconsign dumps the entire contents of the sconsign file(s).
16       Without options, individual dependency entries are printed in the
17       following format:
18
19           depfile: signature timestamp length
20                   implicit_dependency_1: content_signature timestamp length
21                   implicit_dependency_2: content_signature timestamp length
22                   ...
23                   action_signature [action string]
24
25       None is printed in place of any missing timestamp, content signature
26       (csig) or build action signature values for any entry or any of its
27       dependencies. If the entry has no implicit dependencies, or no build
28       action, those lines are omitted.
29
30       By default, sconsign assumes that any file arguments that end with a
31       .dblite suffix contains signature entries for more than one directory
32       (that is, was specified by the SConsignFile function). Any file
33       argument that has no suffix is assumed to be an old-style sconsign file
34       containing the signature entries for a single directory. If neither of
35       those is true, sconsign attempts to guess the format. If that does not
36       work, an explicit format may be specified using the -f or --format=
37       options.
38
39       If there are no file arguments, the name .sconsign.dblite is assumed by
40       default.
41

OPTIONS

43       Various options control what information is printed and the format:
44
45       -a, --act, --action
46           Prints only the build action information for all entries or the
47           specified entries.
48
49       -c, --csig
50           Prints only the content signature (csig) information for all
51           entries or the specified entries.
52
53       -d DIRECTORY, --dir=DIRECTORY
54           When the signatures are being read from a .dblite file, or the -f
55           dblite or --format=dblite options are used, prints information
56           about only the signatures for entries in the specified DIRECTORY.
57
58       -e ENTRY, --entry=ENTRY
59           Prints information about only the specified ENTRY. Multiple -e
60           options may be used, in which case information about each ENTRY is
61           printed in the order in which the options are specified on the
62           command line.
63
64       -f FORMAT, --format=FORMAT
65           The file(s) to be printed are in the specified FORMAT. Legal values
66           are dblite (the SCons.dblite format used by default, as well as
67           when the SConsignFile function is called, except when a filename
68           argument of None is given) and sconsign (the format used for an
69           individual .sconsign file in each directory).
70
71       -h, --help
72           Prints a help message and exits.
73
74       -i, --implicit
75           Prints the list of cached implicit dependencies for all entries or
76           for the specified entries.
77
78       --raw
79           Prints a pretty-printed representation of the raw Python dictionary
80           that holds build information about individual entries (both the
81           entry itself and its implicit dependencies). An entry's build
82           action is still printed in its usual format.
83
84       -r, --readable
85           Prints timestamps in a human-readable string, enclosed in single
86           quotes.
87
88       -t, --timestamp
89           Prints the timestamp information for all entries or the specified
90           entries.
91
92       -v, --verbose
93           Prints labels identifying each field being printed.
